Skylab 1-G Trainer

See how astronauts prepared for America’s first space station. Originally located in Building 5 at Johnson Space Center, the Skylab 1-G Trainer now has a permanent home at Space Center Houston. The Trainer is so big we couldn’t even fit it through the door. Space Center Houston was actually built up around it. With a volume of nearly 300 cubic meters, this is the largest artifact at Space Center Houston. It’s also completely awesome.
